Synapticon > SOMANET Servo Drives


Synapticon SOMANET ultra-compact, high performance embeddable servo drives feature the highest current density in the market. They come fully equipped with all direct connectors, many feedback interfaces, complete protection, frameless EMC, certified functional safety and second to none integration support.

SOMANET Servo Nodes support all PMSM / Synchronous AC / BLDC motors up to 60V and feature an EtherCAT or CAN interface with CiA 402 DS protocol. Upon request, SOMANET drives can be equipped with standard Ethernet, PROFINET, SERCOS III and can also support Brushed DC motors.

Smart algorithms for superior performance with
any electro-mechanics your application needs. 

Synapticon’s proprietary control technologies, such as Model-predictive Field-oriented Control, allow a low heat dissipation of the drives while keeping up high motion control frequencies, which are needed by precision robotics. Advanced disturbance compensation for sensor noise, non-linearity and torque ripple enable high quality motion even with medium to low cost motors and sensors.

All functions of SOMANET Servo Nodes can be configured and tuned with OBLAC Tools, a simple to use yet powerful commissioning and motion tuning tool.

SOMANET Safe Motion  allows for SIL3 PLe level safe motion functions over FSoE (FailSafe over EtherCAT).

SOMANET Product Family

Extra-low voltage for the leading-edge

Mobile robots run on batteries. Collaborative robot arms need to be intrinsically safe for humans. Beyond these reasons for safe-voltage (< 60 Volt) over higher voltage drives, comes Synapticon's progressive, miniaturized inverter designs that use the most advanced power switches available. 

High-definition measurements for great efficiency

Who sees more is in better control: High-speed and high-resolution motor phase monitoring is the base for Synapticon’s Model-Predictive Field-Oriented Motor Control technology. Constantly computing a model of the connected motor, this software always holds a spectrum of control strategies to adopt to the current load situation and perfectly respond to the motor’s exact geometry. The result: perfectly smooth and quiet drives as well as lowest heat-dissipation.

Intelligence to the drives

Synapticon drives can interface to a broad range of feedback encoders, torque and force sensors or even can read touch-sensitive skins and interpret LiDAR data (custom solutions). As they also allow advanced users to run custom software code locally, the computation of kinematic functions and the implementation of local reflexes based on sensor events and custom algorithms become possible on the servo drive.

SOMANET Servo Node Series

A range of ultra-compact, high-performance servo drives for a diversity of applications. A Servo Node consists of three Modules: Communication (Com), Processor (Core) and Drive Module. For each of these Modules, there are several standard options available. Custom Modules can be designed upon special request.

Decentralize to become cabinet-free

Synapticon’s servo drives are among the most compact power electronics in the world. The drives can be integrated right next to the motors in a robot arm or inside a servo motor. Safety functions, and additional sensors can be integrated and the number of wires is reduced from hundreds to only six: one DC power bus and one communication line. Expensive shielding and wear protection becomes obsolete. Cables never need to be maintained again. Product design becomes simpler. Robot or machine system cost reduces.

SOMANET Circulo Series

The Circulo Series is a new class of SOMANET servo drives. With their circular shape and hollow shaft with a diameter of 20 – 40mm, they are ideal for fully integrated motion axes such as in Collaborative Robots and Smart Actuators and revolutionize the world of compact servo drives by integrated encoders.
Circulo Modular Architecture

Worlds first industrial standard for collaborative robots 

For the first time in a standard servo drive: all the needs of a Cobot axis. Circulo Nodes can have up to two integrated encoders (17-18 bits) with a battery-based multi-turn option which automatically calibrates. In addition, the nodes offer onboard security features such as STO and SBC via a 24V I/O. Because the cable connections can easily be looped through, the wiring for EtherCAT, Logic Voltage, STO and SBC are extremely simple. In addition, there is an interface to external encoders for ABZ, SSI, BiSS-C and A-format. Circulo also offers an interface and mechanical device for a Cobot-type locking brake and a motor temperature sensor (PT100, PT1000, KTY).

OBLAC Configuration & Tuning Tools

With Synapticon‘s OBLAC Drive Tool, configuring and tuning a SOMANET Node to work with any PMSM / Synchronous AC / BLDC motor up to 60V from any manufacturer is very easy.

Custom Servo Drive Designs

There can be many reasons why a standard module doesn’t fit an application. Special feature requirements that are not covered by the standard SOMANET drives, low-cost targets particularly in mass applications, need for tight mechanical integration: Synapticon‘s SOMANET Servo Cores, being also at the heart of a standard SOMANET dirve, enable for custom designs. Synapticon’s Custom Design Services are there to carry out this development for you fast and efficiently. High-volume customers have the option to perform design and production of custom SOMANET modules in-house with own resources: SOMANET hardware and software source files are being made available to such clients and SOMANET Servo Cores are supplied to their in-house production.
